With v1.1 populated, I was able to interface with the MAC+PHY chip via the parallel interface and begin sending download rate data over the serial port. I wrote a Python program to plot the data, and compared it with the bandwidth graphs provided by DD-WRT on the router. To my delight, the plots track pretty closely.
